The occurrence of co-tolerance to four heavy metals was investigated among seedlings selected from three different non-tolerant Canadian and German Deschampsia cespitosa (L.) Beauv. populations. Plants selected following screening of seedlings in solution containing Ni or Zn ions, subsequently showe...
